7 * <p>
8 * We reserve no legal rights to the ANTLR--it is fully in the
9 * public domain. An individual or company may do whatever
10 * they wish with source code distributed with ANTLR or the
11 * code generated by ANTLR, including the incorporation of
12 * ANTLR, or its output, into commerical software.
13 * <p>
14 * We encourage users to develop software with ANTLR. However,
15 * we do ask that credit is given to us for developing
16 * ANTLR. By "credit", we mean that if you use ANTLR or
17 * incorporate any source code into one of your programs
18 * (commercial product, research project, or otherwise) that
19 * you acknowledge this fact somewhere in the documentation,
20 * research report, etc... If you like ANTLR and have
21 * developed a nice tool with the output, please mention that
22 * you developed it using ANTLR. In addition, we ask that the
23 * headers remain intact in our source code. As long as these
24 * guidelines are kept, we expect to continue enhancing this
25 * system and expect to make other tools available as they are
26 * completed.
